In this video series I show you how to determine a line that is parallel or perpendicular to another line through a point.

Forces are everyday interactions. They are pushes and pulls that act on objects and are responsible for a change in either an object's motion, shape or both. Forces are measured in newtons ...

Learn the proper culvert design, size, materials and procedures for safe travel over streams and ditches. Culvert installation will run smoothly if you follow this advice. Small streams often ...

Excavation unloading significantly contributes to rock slope failure in an open-pit mine. At present, there is no relevant theoretical study on the failure mechanism of the rock slope under excavation ...

Slope-stability assessment involves the location of the critical slip surface and the corresponding factor of safety (FOS). Considering force-vector characteristics, the vector sum method was further ...

In the 1950s, four decades before he won a Nobel Prize for his contributions to game theory and his story inspired the book and film “A Beautiful Mind,” the mathematician John Nash proved one of the ...

The symmetry argument does not provide any details about the microscopic mechanisms behind the current-induced effective fields seen in the hysteresis loops. In principle, in addition to new ...

We examine the effect of vacancies on the phase behavior and structure of systems consisting of hard cubes using event-driven molecular dynamics and Monte Carlo simulations. We find a first-order ...

We report the detailed mechanical characterization of individual amyloid fibrils by atomic force microscopy and spectroscopy. These self-assembling materials, formed here from the protein insulin, ...
